Celestial navigation - Astronavigation

Sight reduction:
- Marcq Saint Hilaire Line of Position, intercept method (p=Ho-Hc, Zn)
- Observed altitude Ho by nautical almanac data
- Local hour angle (LHA)
- Plot of the LoP on Google maps

Sight reduction is the process of deriving from a sight the information needed for establishing a line of position.
This app is a calculator to get the intercept from the assumed position of the observer AP(latitude, longitude), the geographical position of the celestial body observed, GP(Dec, GHA), and its corrected altitude Ho.
Manual and examples in the developer's website.
